What's New for 2023?
The V-8–powered GT63 and GT63 S models are back for 2023 after taking a year-long break. These high-performance variants of the GT sedan receive the same styling updates that the GT43 and GT53 models received last year. In addition, a range-topping GT63 S E-Performance model joins the lineup with a whopping 830-horsepower plug-in hybrid powertrain.
Pricing and Which One to Buy
We'd suggest going with the mid-range GT53, which offers plenty of horsepower and a pleasant driving experience. We'd add the Warmth and Comfort package, which adds a heated steering wheel, heated front armrests, and rapid-heating elements for the front seats. The Driver Assistance package is also appealing, as it adds a host of technologies including adaptive cruise control, lane-keeping assist, and blind-spot monitoring. Then again, we were seduced by the 630-hp GT63 S when we last drove it.
Engine, Transmission, and Performance
Under the hoods of both the GT43 and GT53 is a robust 3.0-liter inline-six-cylinder engine that features a turbocharger, an intercooler, an electric supercharger, and a small electric motor. From a stop, the electric motor and supercharger fill in the brief lapse in torque delivery before the turbo is spinning out full boost. The 3.0-liter, which packs a combined 429 horsepower in the GT53, snaps necks whenever you touch the accelerator. In our testing the GT53, which features a conventional nine-speed automatic transmission, it accelerated to 60 mph in 4.1 seconds, and its sporty suspension delivered flat, responsive cornering and sports-car levels of grip. The GT63 and GT63 S are powered by a thunderous 4.0-liter V-8. It’s a technological tour de force with dry-sump oiling, direct injection, and two turbochargers mounted in its V. It's rated at 575 horsepower in the GT63, and cranked up to 630 horsepower in the GT63 S. These models also get a dual-clutch nine-speed automatic transmission and air suspension. In our testing, the GT63 S needed just 2.9 seconds to reach 60 mph. That's as quick as a Porsche Panamera Turbo. An even more powerful GT63 S E-Performance plug-in hybrid model has been confirmed for 2023 and uses a rear-mounted electric motor to boost combined horsepower to a 830 hp. Tarmac everywhere need be worried.
Fuel Economy and Real-World MPG
With such extreme performance, it's no surprise the Mercedes-AMG GT sedan is thirsty, but its EPA fuel-economy estimates aren't as dire as you might expect. Both the GT43 and GT53 are rated for 19/25 mpg city/highway; a GT53 model returned 27 mpg in our 75-mph highway fuel economy test. Ratings for the twin-turbo V-8 models have not yet been released. ...
